Most people should know about this group, if not I'll give you the quick info that I've studied in a book of lost/forgotten civilizations. Basically, they are the original Japanese, tribes of "white" people who first populated Japan, but were forced to the fringes by invading samuri and whatnot. They now have since dwindled to about 14,000 and through interbreeding are basically no more.

What I found most interesting is that their culture, from their bone harpoons and carved figurines to their clothes and diet is similar to the "Native" American people, who are very similar in appearance to Polynesians. A little side theory of mine is that these Ainu may have influenced island people through their dispersal and then eventually these island people, perhaps some of the Polynesians of Hawaii even, took their new found way of life and sailed to North America, and through time became what people believe to be "Indians", or "Native Americans".

I'm not sure if I'm leaving something critical out but I would love to hear other people's opinions on this, or even more information on the Ainu or similar people like the Cossacks of Russia/Hungary.

P.S. A little bit of something that's been bothering me ever since the Afros used this excuse of human origin; if we did all "start in Africa" it does not mean we're all part of the Black race... Any thoughts on that too? (both religious and scientific please).

Of course originating in Africa doesn't mean we are black. All other races, who left Africa, developed and evolved from the original homo sapiens of Africa. Even still, I'm quite sure that man left Africa before evolving into homo sapiens, considering that older species of us have been found elsewhere. Therefore all races share common ancestors, but it doesn't mean we are the same. It means that all races which went out of sub-Saharan Africa developed more, which is obvious in terms of achievements and quality of civilization.

As for the Ainu, I didn't know about them. Interesting stuff, I always thought that some Japanese people have a vaguely white facial structure, other than the eyes, such as the actor Toshiro Mifune (Seven Samurai, tons of Kurosawa movies). This verifies that idea.

BTW, samurai did not exist that long ago. They appeared at roughly the beginning of the time when Europe started it's Middle Ages.

The Amazonian tribesmen and a few other western hemisphere inhabitants do appear more Polynesian than the native American indians.
Some, like the Incas and Nazcas, look like the usual indian tribes of North America, but the Aztecs bear more of a Polynesian look.

It's assumed that the Polynesians only made it as far as Easter Island, but further DNA and genetic matching may prove they got all the way to south and central America.
The Aztec and Mayan temples may have been built using a similar method as the giant Moi heads of Easter Island.
There are other structures using similar building styles in south America, but nothing in north America.

I think there's a mix of Polynesians sailing across the Pacific and North American indian/Eskimos coming over the Bering land bridge.
